Durable Golf Tee Construction

ABSTRACT

A durable golf tee construction to prevent the loss of or damage to golf tees, allowing golf players to play many rounds of golf using only one golf tee. The first tee of the duo-tee construction contains a wire connected to the base top and the separable ball seat, through a center hole in the middle ring portion, so that the whole structure becomes more durable and thus environmental friendly than other prior art disclosure&#39;s teaching.

This application is a Continuation-In-Part (CIP) application, under 37 CFR 1.53(b), of a prior parent application Ser. No. 10/907,580, by the same inventors, to supplement the disclosure re the matter related to “Durable Golf Tee Construction”. Present CIP application claims priority of the filing date of Apr. 6, 2005 for the content already disclosed in the prior application, per the requirements of 35 U.S.C. § 120 and 37 C.F.R. 1.78.

FIELD AND BACKGROUND OF THE INVENTION

The present invention relates generally to design and construction of durable and reusable golf tees. The main advantage of present invention helps to reduce the loss of or damages to the golf tee, and therefore, has great environmental value.

Golf tees traditionally are simply a wood stick with a widened seat on top for the ball to be placed. Although tees are relatively inexpensive and golfers usually carry a package of them in the golf bags, golfers sometimes run into problems when these one-time-use tees are used up in a game.

Present invention provides a durable golf tee that allows golf players to carry only ONE tee of present invention and do not need to worry about buying a bunch of tees again and again.

Because golfers need not repeatedly buy those one-time golf tees, present invention also has high environmental value in reducing wasted material.

OBJECTS AND SUMMARY OF THE INVENTION

Present invention has a unique construction for a first tee having separable ball seat portion, so that the tee will not be damaged by golf swings.

Furthermore, a string is utilized to connect the first separable tee to a second tee, so that even when the first tee is hit up in the air, the string along with the second tee actually pull back and stop the first tee from flying out and disappear into any long grassy area on or around the tee-off box in the golf course.

The string used to connect the separable first tee and the second tee also helps to create a line for golfers to visualize and provides a good guidance for improving golf games.

The ball seat of the first tee is separable from, but connected to the middle ring portion and base by a combination of a wire and spring, creating the desired structure to withstand hitting and quick restoration to original shape.

Present invention has great advantage over prior art patent by inventor Hyung Choon Lee, U.S. Pat. No. 6,783,470 (Lee 470 Patent) in that:

(1) said Lee 470 Patent uses a clevis pin (8) to connect the ball seat to the base; often times these hard pins tend to break.

(2) said Lee 470 Patent is a two-piece construction, whereas present invention is a three-piece construction, allowing the better string attachment and more durable tee than Lee 470 Patent.

(3) said Lee 470 Patent provides no bevel angle at the junction of top ball seat and the base, so that there is more resistance for break-away action (at time of club head impacting the tee) and the restoration (from the break-away ball seat back to the base) requires more alignment effort.

(4) said tee of Lee 470 Patent could become lost in the grass, just like other regular tees, lacking the string/second tee pulling of present invention, which ensures golfers will always be able to locate the tee.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Present invention uses the prevalent rubber or plastic material as the main ingredient for the production of the middle ring portion. These materials include, but are not limited to, PE, PVC, PU, etc., and help to enhance the durability of present invention. The technique of plastic/rubber injection to form the middle ring portion, as well as the making of said plastic/rubber, are commonly found practices and need no disclosure herein.

FIG. 1 shows a first tee 100, connected to a second tee 200, by a string 150. By using this pair of tees connect by a string 150, golfers will be able to locate the tee after striking the ball (sitting on top of the tee), because the tee being struck upon (whether it's tee 100 or tee 200, depending on the use), the other tee will pull back the “flying out” action of the tee being struck upon. The string 150 can be made of bright color and thus helping to locate the tee construction.

FIGS. 2 a and 2 b show the breakable/separable construction of first tee 100. First tee 100 is further made up of 3 main parts: ball seat 80, middle ring portion 50 and base 20. Ball seat 80 has an inner hollowed out space to receive a spring 86 and a wire 83.

Middle ring portion 50 has an upright protruding 51 that is sized to snugly receive the opening of the inner hollowed out space of the ball seat 80, easily aligning the ball seat 80 to the middle portion 50 and the base 20, as shown in the assembled view of FIG. 2 a.

An upper end-clamp 839 and a lower end-clamp 831 are used to secure said wire 83 in place, so that the upper end of wire 83 will pull and compress said spring 86 towards the base, at time of impact from a golf swing.

Lower end claim 831 of wire 83 is attached, through a hole in the middle ring portion 50, directly to the base top 28. This arrangement of wire 83 connection produces more durable breakable ball seat 80 movements, than otherwise is the case, as achieved by other prior art disclosure, such as the Lee 470 patent.

FIG. 3 a shows the separable ball seat 80 of first tee 100 can be slanted and swayed as struck upon by golf clubs. When a golf player hits the ball, the ball seat 80 will be momentarily slanted, wire 83 pulls back the spring 86, so that the spring 86 will be in a state of compression, exerting force to restore to the spring's original uncompressed state. Such a construction allows the first tee 100 to absorb the impact of a golf swing and hit by breaking away, yet remains connected by the wire 83 and then quickly restore its previous state due to the spring's 86 resilient force.

FIG. 3 b shows that first end-clamp 831 further has a groove G, to mesh with the cave slot 28 on top of said base.

As shown in FIGS. 3 b(1) and 3 b(2), first end-clamp 831 is “grabbed into” said cave slot 28 nice and tightly. After the plastic (or rubber) injection process, to form the middle ring portion 50, the connection of end-clamp 831 to cave slot 28 is made really strong and durable.

Said cave slot 28 and said base 20 is made from a same metal piece via precise lathing process, so that when plastic (or rubber, depending on implementation choice) material is injected over the clamped together combo of cave slot 28 and first end-claim 831, it forms an extremely strong holding power to retain the wire 83.

Furthermore, as shown in FIG. 3 b (3), said protruding 51 is made to have a bevel angle BA, so that there is less resistance at the time of ball seat 80 break-away (when clubhead is impacting the golf ball) and the automatic restoration of ball seat 80 to the protruding 51 is made easier, due to the bevel angle BA.

This bevel angle BA is an advantage of Lee 470 patent, where the base of said two-piece construction contains a 90-degree protrusion for insertion into ball seat, for purpose of breakaway and restoration.

FIG. 4 shows the string 150 can be used to help line up golfer's swing, creating more utility for present invention. Depending on preference, golfers can switch the two tees and use the second tee 200 as the ball-striking tee, so that the ball sits lower and closer to the ground, creating better hitting surface more akin to using iron shot than a driver (using woods).

FIG. 5 shows the middle ring portion 50 has extended outer circumferential edge (as marked by letters a and b) to allow better and convenient handling by human figures.
